Hunter Capital Research report, page-15

Apart from what @densamer posted, I can't say. A scoping study is a rough desk-top estimate rather than a hard-core feasibility study. However, since MYL might receive the metallurgical testing results at the same time as the JORC is completed, the metallurgical results might tightened up the scoping study due to providing more accurate assessment of metallurgical recoveries. However, as i said, a scoping study is only a rough estimate of opex & capex usually based on analysing the feasibility outcomes of other comparative projects, as found in the analyst report.
